Abstract

The aim of this study was to compare the reliability, internal responsiveness and interchangeability of the Yo-Yo intermittent recovery test level 1 (YY1), level 2 (YY2) and submaximal YY1 (YY1-sub). Twenty-four young soccer players (age 17 ± 1 years; height 177 ± 7 cm; body mass 68 ± 6 kg) completed each test five times within pre- and in-season; distances covered and heart rates (HRs) were measured. Reliability was expressed as typical error of measurement (TEM) and intraclass correlation coefficient (ICC). Internal responsiveness was determined as effect size (ES) and signal-to-noise ratio (ES_TEM). Interchangeability was determined with correlation between training-induced changes. The TEM and ICC for distances in the YY1 and YY2 and for HR in YY1-sub were 7.3% and 0.78, 7.1% and 0.93 and 2.2% and 0.78, respectively. The ESs and ES_TEMs were 0.9 and 1.9 for YY1, 0.4 and 1.2 for YY2 and ?0.3 and ?0.3 for YY1-sub. Correlations between YY1 vs. YY2 and YY1-sub were 0.56 to 0.84 and ?0.36 to ?0.81, respectively. Correlations between change scores in YY1 vs. YY2 were 0.29 and ?0.21 vs. YY1-sub. Peak HR was higher in YY1 vs. YY2. The YY1 and YY2 showed similar reliability; however, they were not interchangeable. The YY1 was more responsive to training compared to YY2 and YY1-sub.  相似文献   

National Sporting Pastimes,Spectacles of Sporting Otherness and American Imaginings, 1880–1920     

David L. Andrews  Jacob Bustad  Samuel Clevenger 《国际体育史杂志》2014,31(1-2):224-249

This discussion focuses on how the rise of America's national sporting pastimes, during the period 1880–1920, was inextricably tied to the ambitions and outpourings of American print capitalism and a concomitant congealing of a sense of modern American nationhood. In examining this thematic, we explicate the manner in which American national sporting audiences during the period 1880–1920 were variously constituted through discourses of national and ethnic sporting difference or Otherness. Hence, we examine the popular representation of turn of the century rodeo practices (as narrated through the spectacle of the western showman William Frederick ‘Buffalo Bill’ Cody's Wild West show productions), the position of early-twentieth-century American baseball in relation to other sporting cultures (graphically depicted by Albert Goodwill, or A.G., Spalding's promotional publications, specifically the 1911 America's National Game) and the national and ethnic differences discerned within the global sporting landscape more generally (explicated within the 1919 National Geographic article ‘The Geography of Games’). These performances and representations of ethnic and national sporting Otherness played an important role in re-inscribing and legitimating the (White European American) normative core of American sport culture (as manifest within and through the dominant practices of playing and/or spectating of football, baseball and basketball).  相似文献   

Lacrosse History,a History of One Sport or Two? A Comparative Analysis of Men's Lacrosse and Women's Lacrosse in the United States     

Melissa C. Wiser 《国际体育史杂志》2014,31(13):1656-1676

Men's lacrosse and women's lacrosse share a name, but their histories differ. Both sports developed and became organised in close concert with the race, class and gender expectations of the eras. As a result, the sports began with rules that reflected those norms. Over time, the sports developed separately and generated unique forms, even as they sustained moments of interaction. Therefore, men's lacrosse and women's lacrosse are different sports. Using comparisons as the mode through which to view the sports, this article explores the organised beginnings of men's lacrosse and women's lacrosse to establish that the sports began and continued within identity-based norms. Through the discussion of the practical distinctions and critical understandings of the differences between the games, the author poses that these dissimilarities are relevant in considerations of the separate sports as they continue to change in the larger US sporting context. As sports such as basketball demonstrate, these arguments matter because broad-scale comparisons of women's sports to men's frequently render women's sport participants, and the sports they play, inferior. Notably, women's lacrosse participants also employed comparisons to distinguish and claim their history as unique from that of men's lacrosse. A comparative analysis highlights points of disjuncture between the sports and contextualises the importance of gender in the articulations of difference.  相似文献

美好乡村环境治理中的政府行为--以安徽乡村为例     

唐建兵 《保定学院学报》2014,(5):61-67

在推进美好乡村建设的进程中,环境治理是其间的一项急迫任务。任务的完成既离不开社会力量的广泛参与,更需要各级政府切实履行职能。一方面需要政府提供保护环境的公共物品,另一方面政府尚需“有所作为、善于作为”。政府尤其是县乡基层政府有所作为,尚需明确并适度强化基层政府的环境治理职能;坚持规划引领、示范带动,稳步推进乡村环境改善;完善基层政府的乡村环境考核激励机制;加大环保宣传力度,着力提升民众的生态环保意识;通过政策扶持、简政放权等多项举措培育民间环保非政府组织。  相似文献

Interpersonal violence against children in sport in the Netherlands and Belgium     

《Child abuse & neglect》2016

The current article reports on the first large-scale prevalence study on interpersonal violence against children in sport in the Netherlands and Belgium. Using a dedicated online questionnaire, over 4,000 adults prescreened on having participated in organized sport before the age of 18 were surveyed with respect to their experiences with childhood psychological, physical, and sexual violence while playing sports. Being the first of its kind in the Netherlands and Belgium, our study has a sufficiently large sample taken from the general population, with a balanced gender ratio and wide variety in socio-demographic characteristics. The survey showed that 38% of all respondents reported experiences with psychological violence, 11% with physical violence, and 14% with sexual violence. Ethnic minority, lesbian/gay/bisexual (LGB) and disabled athletes, and those competing at the international level report significantly more experiences of interpersonal violence in sport. The results are consistent with rates obtained outside sport, underscoring the need for more research on interventions and systematic follow-ups, to minimize these negative experiences in youth sport.  相似文献
